Fix the framing automatically
This checker measures your raw photo. To actually fix the framing, open the free editor — it detects your face, crops to your country's exact head-size band and eye-line position, removes the background, and exports print-ready files. See also the full compliance checker for background, lighting, and resolution checks.
Head size rules — FAQ
What head size do passport photos require?
Most countries follow ICAO guidance: the head (chin to crown) should fill roughly 70–80% of the photo height — for a 35×45 mm photo that is 32–36 mm. The US 2×2 inch photo wants the head between 1 inch and 1 3/8 inches (25–35 mm), about 50–69% of the frame. The UK is stricter at 29–34 mm. Wrong head size is one of the most common rejection reasons.
How does this checker measure my head?
A small (~2MB) face-detection model runs in your browser, finds your face and eye positions, and estimates the full chin-to-crown head height (detectors see eyebrows-to-chin, so the crown is extrapolated). It then reports the head height as a percentage of your photo frame and marks everything visually so you can sanity-check it.
My photo "failed" — do I need to retake it?
Not necessarily. If the head is too SMALL in the frame, the photo usually just needs tighter cropping — the free editor does that automatically to your country's exact spec. Only if the head is too LARGE (not enough space above the crown) or blurry after cropping do you need to retake from further away.
Is my photo uploaded for analysis?
No. The face detection model downloads to your browser and runs on your device. The photo never leaves your computer or phone — the same privacy model as our whole editor.
